There's no need to worry about calling Bruce Willis and Ben Affleck to blow this one up, but it should be pretty cool to watch this huge asteroid pass by earth today.

The asteroid 2004 BL86 will do a fly by of Earth at about 1.2 million kilometers, or three times the distance of the moon. There have been asteroids in recent history that have flown closer to earth, but the size of this one makes it special.
